The document describes a proposed final project called Lock and Key, a motion-controlled puzzle game for the Nintendo Wii. Players must collaborate to solve puzzles, clear levels, and collect broken pieces of their home ship to escape an alien world. The game aims to provide "easy" and "serious" fun through curiosity, wonder, surprise, awe, focus, excitement, and relaxation. It will utilize intuitive motion controls like Wii Sports and Elebits. Players will progress through a three-act structure with worlds containing three levels each to introduce new mechanics and allow players to learn, practice, and master skills through collaboration.
